Rhythm 5-6-oh (TweetTweetJam)

A game made in 560 characters for TweetTweetJam 4. The sound effects are generated from the poke commands at the top. The note pattern is random and can be a little unfair at times. I wanted to try a smarter way to generate the notes, but with 560 characters, there's not much room.
